  • Patent number: 8256470
    Abstract: A multi-layer ballistic woven fabric, including an upper woven layer having upper warp yarns and upper weft yarns that are interwoven together to form the upper woven layer. The multi-layer ballistic woven fabric also includes a lower woven layer having lower warp yarns and lower weft yarns that are interwoven together, and a plurality of securing yarns, each securing yarn interwoven with at least some of the upper yarns and some of the lower yarns so as to secure the upper and lower woven layers together. At least one of the securing yarns is woven underneath a first lower weft yarn, then above a second upper weft yarn adjacent the first lower weft yarn, then underneath a third lower weft yarn adjacent the second upper weft yarn and then above a fourth upper weft yarn adjacent the third lower weft yarn. The multi-layer ballistic woven fabric is formed by interweaving the securing yarns with the warp yarns and weft yarns as the upper woven layer and lower woven layer are made.

  • Patent number: 7820565
    Abstract: A fabric including a first layer of high-performance unidirectional yarns and a second layer of high-performance unidirectional yarns disposed transversely to the first layer. The fabric also includes warp and fill encapsulating yarns woven around the unidirectional yarns to substantially stabilize the unidirectional yarns. The encapsulating yarns have tenacities and tensile moduli substantially less than the tenacities and tensile moduli of the unidirectional yarns. The fabric has a cover factor between approximately 0.75 and approximately 1.50.

  • Publication number: 20080268733
    Abstract: According to some aspects, a method of manufacturing a coated multi-threat fabric, including providing a first fabric layer having a first surface, the first fabric layer having a plurality of high performance fibers, applying a first polymeric material onto the first surface of the first fabric layer, the polymeric material having a melt flow index of between about 0.7 to 1400 g/10 min, a Shore D hardness of between about 36 and 75, and ultimate tensile strength of between about 5 and 75 MPa, spreading the first polymeric material onto the first surface of the first fabric layer so as to form a raw coated fabric having a first coating layer, and heating the raw coated fabric to bond the first coating layer to the first fabric layer, wherein the first polymeric material is selected such that the coated multi-threat fabric is flexible enough to be stored on a roll of a predetermined size.

  • Publication number: 20030109188
    Abstract: A laminated fabric for penetration resistant e.g. ballistic applications. The fabric comprising a fabric of penetration resistant yarns having a linear density in the range from 100 to 700 dtex, said yarns being woven in a satin weave. The woven fabric is coated on at least one-side with a polymeric material in a micro-lamination process, the coating material being from 0.
